Tilting, the upper Z axis may be in a lowered position (ie, the hatch of the lower chamber 200 and the upper chamber 100 is closed). In addition, the clamp unit 240 may be in a state where the film is fixed through rising-forward-falling.

More specifically, the clamp unit 240 may prevent and fix the movement of the film during vision alignment check using a vision camera. The clamp unit 240 may move forward or backward and move upward and downward to fix the film according to driving.

For example, the clamp unit 240 may move forward or backward through cylinder control and may move up and down through cylinder control. As such, the clamp unit 240 may move forward and downward in a state in which the clamp unit 240 is moved backwards and upwards, and thus both sides of the clamp unit 240 may press the film equally to fix the film. The clamp unit 240 is fixed to the upper plate of the Auto Alignment System (Auto Alignment System) 230, so as to move as a film during alignment can be aligned 1: 1 with the upper glass.

FIG. 8 is a view illustrating a clamp state of an apparatus for bonding a film by using thermal transfer to a surface of a liquid crystal panel having a side curved surface according to an embodiment.

Referring to FIG. 8, the clamp unit 240 is fixed to the upper plate of the Auto Alignment System 230 and moves in the forward and downward directions so that both sides press the film in the same manner to fix the film.

After the upper chamber 100 and the lower chamber 200 move to the lamination position, lamination may begin. Chamber vacuum may be started in the internal spaces 110 and 210 formed by the combination of the upper chamber 100 and the lower chamber 200. At this time, since the upper chamber 100 and the lower chamber 200 are coupled to each other, the upper chamber 100 and the lower chamber 200 are sealed from the outside, and the air inside the upper chamber 100 and the lower chamber 200 is discharged to the outside to bring the interior into a vacuum state. It can be maintained.

As the upper chamber 100 and the lower chamber 200 are moved to the lamination position, the hatch of the lower chamber 200 and the upper chamber 100 is closed, and the lower silicon pad 220 is applied to give tension of the film. The predetermined height can move up. In this case, the film disposed on the silicon pad 220 and the glass jig 120 of the upper chamber 100 may be bonded to each other. The heater 121 of the glass jig 120 of the upper chamber 100 continuously heats the glass to be neatly and accurately bonded to the side curved portion without generation of bubbles.

In other words, the film disposed on the upper portion of the silicon pad 220 is moved in a direction approaching the glass disposed in the upper chamber 100 as the silicon pad 220 rises, thereby bonding the glass and the film to each other. The heater 121 of the glass jig 120 may continuously heat the glass to help the bonding operation.

Here, the bonding operation of the glass and the film is a problem that is a problem when rolling the existing equipment by laminating the film disposed on the upper portion of the silicon pad 220 to the glass of the upper chamber 100 1: 1 at the bottom. And Align problem can be solved.

The inner spaces 110 and 210 of the upper chamber 100 and the lower chamber 200 are clamped, and the glass and film are bonded by keeping the inner spaces 110 and 210 in a vacuum state. Bubbles and dust can be prevented in the process. For example, the vacuum state of the internal spaces 110 and 210 formed by the combination of the upper chamber 100 and the lower chamber 200 may be 100 mPa.

(Tilting), 상부 Z축은 하강위치(즉, 하부 챔버(200)와 상부 챔버(100)의 해치 닫힌 상태)일 수 있다. 그리고 클램프 유닛(Clamp Unit)은 실리콘 패드(220)가 기설정된 정도만큼 상승하는 경우, 클램프(Clamp) 상태에서 클램프 해제(Un Clamp) 상태로 변경시킬 수 있다. Here, the Y axis of the Auto Alignment System 230 is advanced (1: 1 position movement with the glass jig 120 of the upper chamber 100), the lower Z axis is raised (glass bonding position movement), the upper T axis

(Tilting), the upper Z-axis may be in the lowered position (ie, the hatch closed state of the lower chamber 200 and the upper chamber 100). When the silicon pad 220 rises by a predetermined level, the clamp unit may change the clamp unit from the clamp state to the un-clamp state.

FIG. 9 is a diagram illustrating a clamp release state of an apparatus for bonding a film to the surface of a liquid crystal panel having a side curved surface by using thermal transfer.

Referring to FIG. 9, the clamp unit 240 may be moved in both directions by the auto alignment system 230 to release the film fixing state.

When the bonding operation of the glass and the film is completed, the external air can be supplied to the inner space by changing from the clamp state to the unclamp state. The silicon pad 220 may be lowered again.

Thereafter, the upper chamber 100 may move upward and prepare for the next work.

As described above, the embodiments of the present invention use a pad method to bond the film to the surface of the liquid crystal panel having the side curved surface by using a pad method. Since the silicon pad 220 is laminated to the upper glass 1: 1 at the bottom, the conventional method is used. It can compensate for the problem of rolling and alignment, which was a problem when rolling the equipment.

FIG. 10 is a perspective view illustrating a heater of an apparatus for bonding a film using thermal transfer to a surface of a liquid crystal panel having a side curved surface, according to an exemplary embodiment. FIG. 11 is a bottom view illustrating a heater of an apparatus for bonding a film by using thermal transfer to a surface of a liquid crystal panel having a side curved surface according to an embodiment.

10 and 11, the glass jig 120 is configured with a heater 121, by transferring the film to the glass by a thermal transfer method to bond the film to the surface of the liquid crystal panel, without generating bubbles in the side curved portion It can be bonded neatly and accurately.

The heater 121 may include a plurality of stick heaters spaced apart from the glass jig 120 by a predetermined interval, and a sensor (temperature control sensor) installed for power management and temperature control of the plurality of stick heaters may be configured. Can be. For example, the plurality of stick heaters may be configured as four stick heaters. This is because, due to space constraints, the stick heater is inserted into the glass jig 120 having a relatively thick thickness in the apparatus, and four stick heaters may be inserted to maintain the maximum temperature at 200 degrees.

Since the heater 121 needs to be heated to give a temperature to the glass and laminated with the transfer film (ink), when the power of the apparatus is turned on, it is preferable that the power of the heater 121 is also turned on, and the heater 121 The temperature of) may vary depending on the product of the liquid crystal panel, film, and the like used.

The temperature control sensor may be configured at the center portion (center of the glass jig 120) in which the heater 121 is inserted. The temperature of the glass jig 120 may be measured through the temperature control sensor, and the temperature may be adjusted through a temperature controller (Temp Controller) located at the top of a separate device. Here, the temperature control sensor may be referred to as a volt sensor.

In this way, the temperature of the plurality of stick heaters can be adjusted through the sensor, and for example, the temperature applied to the glass can be controlled by enabling the temperature of the plurality of stick heaters to be used up to 200 degrees.

Through the above-described apparatus using the thermal transfer method, which supplements the disadvantages of the conventional film adsorption method, it is possible to increase the transmittance and reduce the unit cost of the film after laminating the film and glass. On the other hand, in the case of the existing Deco film laminated type (adhesion) by applying a vacuum and pressure conditions without heating to the film or glass part, but according to the embodiment by attaching the film by transferring the film to the glass using a thermal transfer method can do. In particular, in order to eliminate bubbles of the four side curved surfaces generated at the time of lamination, lamination can be enabled using a heater.
